Description

Camera device, driver assistance system, and vehicle

Technical Field

The present invention relates to a camera device, including: a first lens designed to form a first light beam _ B when the first light beam _ a passes through; a first sensor, wherein the first sensor is arranged in the first light beam _ B, wherein the first sensor is designed to convert the first light beam _ B impinging on the first sensor into first ambient image data; at least one second lens designed to form a second light beam _ B when the second light beam _ a passes through it; at least one second sensor, wherein the at least one second sensor is arranged in the second light beam _ B, wherein the at least one second sensor is designed to convert the second light beam _ B impinging on the at least one second sensor into second ambient image data. The invention also relates to a driver assistance system with such a camera arrangement and to a vehicle.

Background

Such devices are well known. Therefore, camera devices are known in which individual images of a plurality of individual cameras are combined to form a general/overview image in order to increase the detection range of the vehicle environment. In this case, expensive cameras, for example with wide-angle lenses, must be used for this purpose. If such a device is used as a rearview mirror replacement system which has to cover a very large Field of view (FOV = Field of view), the lens resolution of e.g. a wide-angle lens is often not sufficient. Wide-angle cameras also have the drawback of significant image distortion, especially in boundary areas.

If a plurality of single cameras are used, the generated camera images have to be combined into a total map, for example by an image processing unit, in order to cover the required detection area. Such a camera arrangement with a plurality of single cameras is also referred to as a panoramic looking around system. A conventional panoramic look-around system for a vehicle may have, for example, four vehicle cameras positioned at the front, rear, left and right sides of the vehicle. The resultant general map may then be displayed to the driver or passenger of the vehicle. In this way, the driver can be assisted in a motor operation of the vehicle, for example during reversing of the vehicle or during a parking operation. The camera images provided by the different vehicle cameras usually overlap in an overlap region.

However, it is not always possible to arrange a plurality of cameras. The use of a plurality of individual cameras leads to a shift in the overall image with respect to motion artifacts, since the orientation of the images is realized by means of so-called Lookup Tables (abbreviated to LUT) which are only suitable for the relative camera position. If the relative camera positions change, the images can no longer be combined correctly.

Document DE 10 2014 210 323 A1 discloses a camera device and a method for adaptive image correction of at least one image parameter of a recorded image, having: a plurality of cameras for converting the camera images, wherein the camera images of adjacent cameras have overlapping image areas; and an image processing unit which combines the camera images generated by the camera into a combined overall picture, wherein the image processing unit has image correction means which, for each received camera image, calculates a plurality of average image parameter levels of the image parameters in the overlapping image regions of the camera images and adjusts the respective image parameters in dependence on the calculated average image parameter levels.

DE 10 2013 200 427 A1 discloses a method and a camera device for generating a panoramic view of a vehicle environment of a vehicle, having: a first vehicle camera for capturing a first environmental subregion of a vehicle environment; a second vehicle camera for capturing a second environmental subregion of the vehicle environment that is at least partially different from the first environmental subregion; at least one first lighting device for illuminating a first environment subregion of the vehicle environment by means of electromagnetic radiation in the visible wavelength range and/or the infrared wavelength range; at least one second lighting device for illuminating a second environmental subregion of the vehicle environment by means of electromagnetic radiation at least in the infrared wavelength range; and a camera device for generating a panoramic all-round image of the vehicle environment of the vehicle.

DE 10 2011 077 A1 discloses a vehicle camera system for providing a seamless image of a vehicle environment by means of one or more camera modules, which each comprise a camera and a local computing unit. The local computing unit is designed to pre-process the vehicle surroundings images captured by the associated cameras and comprises at least one analog output for signal transmission. The vehicle camera system has an image fusion unit which is designed to generate at least one seamless overall image of at least one region of the vehicle environment on the basis of the preprocessed vehicle environment image transmitted in a simulated manner by means of the simulation output of the local computing unit.

Disclosure of Invention

The object of the present invention is to provide an improved and simplified camera device, an improved driver assistance system and an improved vehicle for detecting ambient image data.

This object is achieved by providing a camera arrangement having the features of claim 1. Furthermore, the object is achieved by providing a driver assistance system having the features of claim 13 and by providing a vehicle having the features of claim 14.

Further advantageous measures are listed in the dependent claims, which can be combined with one another as desired in order to achieve further advantages.

This object is achieved by providing a camera arrangement comprising: a first lens designed to form a first light beam _ B when traversed by the first light beam _ a; a first sensor, wherein the first sensor is arranged within the first light beam _ B, the first sensor being designed to convert the first light beam _ B impinging on the first sensor into first ambient image data;

at least one second lens designed to form a second light beam _ B when traversed by a second light beam _ a; at least one second sensor, wherein the at least one second sensor is arranged within the second light beam _ B, the at least one second sensor being designed to convert the second light beam _ B impinging on the at least one second sensor into second ambient image data.

In the scope of the invention, the first sensor and the at least one second sensor are arranged in a common housing, wherein the first sensor is arranged outside the second beam _ B and the at least one second sensor is arranged outside the first beam _ B,

wherein the first lens and the first sensor and the at least one second lens and the at least one second sensor are arranged such that the first beam _ B and the second beam _ B partially overlap in the housing.

The lens is to be understood as both a single lens and the entire lens system, in particular the lens can be configured as a camera lens. For example, the lens system may be a plurality of lenses arranged in succession with a converging and/or diverging effect. Similar considerations apply to the sensor. For example, each sensor may also be an array of sensors.

By arranging the first sensor and the at least one second sensor in a common housing, installation space can be saved. This simplifies the integration of the machine into other components, for example, vehicle components. Furthermore, energy consumption and heat emissions can be reduced. By arranging the first sensor outside the second light beam _ B and the at least one second sensor outside the first light beam _ B, the intersecting light beams _ B can be avoided from interacting with each other. Image artifacts can thereby be avoided. The light beam _ B is preferably designed as a light cone.

By connecting the two sensors, a single data transmission interface can be used for transmitting the generated ambient image data. Using a data transfer interface in the form of a single cable instead of multiple data transfer cables results in a reduced weight and lower complexity of the camera device.

According to the invention, relative movements between the sensors are avoided, which can lead to loss of detail or incorrect illustration of the image.

The use of a camera device enables the use of a plurality of different sensors in a common housing. The invention simplifies the position calibration of the lens and the sensor relative to each other.

Preferably, the first lens and the at least one second lens are arranged in or on a common housing. By arranging the first sensor and the at least one second sensor in a housing and the first lens and the at least one second lens in or on a single common housing, individual image angle areas/fields of view (FOV) can be covered by a single camera device. The backward view and the forward view can be generated, for example, by a single camera device. Thereby eliminating the use of multiple single cameras. Furthermore, only a unique calibration of the camera device is required. This saves cost and time.

In a preferred embodiment, the first lens forms a first optical axis with the first sensor and the at least one second lens forms a second optical axis with the at least one second sensor, wherein the first lens, the first sensor, the at least one second lens and the at least one second sensor are arranged such that the first optical axis and the second optical axis intersect within the housing.

Advantageously, the first lens points in a first direction and the at least one second lens points in a second direction different from the first direction. This makes it possible to cover in particular a large field of view/image angle region.

Preferably, the first sensor and/or the at least one second sensor are/is configured as a one-dimensional, two-dimensional or three-dimensional image sensor. In this case, 1D measurements can be carried out by means of one-dimensional image sensors, for example for distance detection, 2D measurements by means of two-dimensional image sensors, for example for two-dimensional object detection, and 3D measurements by means of three-dimensional image sensors, for example for three-dimensional environment detection. The first sensor and the at least one second sensor may be designed identically or differently. The first Sensor and/or the at least one second Sensor may be embodied, for example, as a CCD (charge-coupled Device) Sensor and/or a CMOS (Complementary Metal Oxide Semiconductor) Sensor and/or a CIS (Contact Image Sensor) Sensor and/or a DPS (Digital Pixel) Sensor. These image sensors have a very high lateral resolution. Furthermore, one of the two sensors or sensors can also be designed as a PMD (photonic mixer) sensor, which detects the distance of the object in addition to the brightness information of the object.

Advantageously, the first sensor is designed as a first semiconductor component comprising a plurality of light-sensitive pixels, and/or the at least one second sensor is designed as a second semiconductor component comprising a plurality of light-sensitive pixels.

Preferably, a flexible circuit board is provided. Furthermore, the first sensor and the at least one second sensor are preferably arranged on a flexible printed circuit board. The flexible printed circuit board, which advantageously has one or more flexible bending sections, can be designed as a rigid-flex circuit board or as a semi-flexible circuit board and is suitable for SMD mounting (surface-mounted components). A rigid-flex circuit board is understood here to be a circuit board having a rigid region and a flexible region; the flexible region may also be formed by a cable. A semi-flexible circuit board (also referred to as a semi-flexible circuit board) is a circuit board with flexible circuit board sections.

Circuit board fixing elements, so-called mechanical guide pins, are also provided in order to ensure the positioning of the flexible circuit board in or on the housing.

In a preferred embodiment, at least one data transfer interface is provided for transferring the first ambient image data and the at least one second ambient image data, by means of which the first ambient image data and the at least one second ambient image data can be transferred for further processing outside the housing. The data transfer Interface may be embodied, for example, as a MIPI (Mobile Industry Processor Interface) Interface or as a POC (Power-Over-Coax) Interface.

In a preferred embodiment, a filter is arranged between the first lens and the first sensor and/or a filter is arranged between the at least one second lens and the at least one second sensor. The filter can be designed in particular as an IR filter (infrared filter, infrared absorption filter), which prevents the incidence of infrared radiation. This prevents interfering influences of infrared radiation on the imaging quality of the first sensor and/or the at least one second sensor.

Preferably, evaluation electronics for the first ambient image data and the at least one second ambient image data are arranged in the housing. Here, the evaluation electronics can be used for data preprocessing of the generated ambient image data. This can result in a reduction of data and thus in a faster transfer. Preferably, the evaluation electronics are connected with an interface arranged at the housing to transfer the preprocessed ambient image data for further processing outside the housing.

In a preferred embodiment, the first lens and the at least one second lens are arranged fixedly in or on the housing, and the first sensor and the at least one second sensor are arranged fixedly in the housing. The lens can in particular be integrated in the housing, i.e. arranged pointing inward, which additionally reduces the installation space.

Preferably, the first lens, the at least one second lens, the first sensor and the at least one second sensor are arranged immovably with respect to each other. Thereby avoiding relative movement of the elements with respect to each other.

The object is also achieved by providing a driver assistance system having a camera arrangement as described above.

Preferably, the driver assistance system comprises: a computing unit configured to process the first environment image data and the second environment image data into an overall environment image; and an indicating device configured to indicate the environment image. The display device may be, for example, an LED display device and is configured to display ambient image data.

The object is also achieved by providing a vehicle having a driver assistance system as described above. The vehicle is in particular a passenger car.

Other features, properties and advantages of the invention result from the following description with reference to the drawings. Wherein:

fig. 1 schematically shows a vehicle, with a vehicle image system according to the prior art,

Detailed Description

While the invention has been illustrated and described in further detail by the preferred embodiments, it is not intended to be limited to the disclosed examples. From which various modifications may be derived by a person skilled in the art without departing from the scope of protection of the invention as defined by the claims.

Fig. 1 schematically shows a vehicle 100 with a vehicle image system according to the prior art for providing a seamless image of the vehicle environment. The vehicle image system has a first camera and a second camera, which are integrated in the exterior mirror 101, for example, according to the prior art. Here, the second camera may have a wide-angle lens. The first camera can be used, for example, to capture an image capture as a forward view of the first image data 102, i.e., to detect the environment in the direction of travel and partially in a side view. The second camera can take as second image data 103, for example, a rearward view, i.e., an image capture opposite to the direction of travel and partially in side view, which detects the environment. Here, an overlap region 104 is provided, which partially has the first image data 102 and partially has the second image data 103. The vehicle image system further comprises an evaluation unit, which is arranged outside the respective camera. The first image data 102 and the second image data 103 are transmitted to the evaluation unit via interfaces present in the respective cameras and are converted into a general diagram in the evaluation unit. The general map may then be displayed to the driver in a display device. However, if such a system is considered as a rear view mirror replacement system, the resolution of the camera is often insufficient. There are also motion artifacts. Each camera in a vehicle vision system must be calibrated before use. If a mechanical position shift occurs in at least one of the cameras, a recalibration is necessary.

Fig. 2 shows a camera device 1 according to the invention. The camera device 1 includes a first lens 2 and a second lens 3. Other lenses may also be present. Furthermore, the camera device 1 comprises a first sensor 4 and a second sensor 5. The first lens 2 is designed to form a first light beam _ B6 when the first light beam _ A8 passes through it. The second lens 3 is designed to form a second light beam _ B7 when the second light beam _ A9 passes through. The first lens 2 is arranged relative to the first sensor 4 such that the first light beam _ B6 impinges on the first sensor 4. The second lens 3 is arranged relative to the second sensor 5 such that the second light beam _ B7 impinges on the second sensor 5. A first filter 10, which filters out light of a certain wavelength range, is preferably arranged downstream of the first lens 2 in the direction of the first sensor 4. The first filter 10 can be designed as an IR filter (infrared filter or infrared absorption filter) which prevents the incidence of infrared radiation. A second filter 11 is preferably arranged downstream of the second lens 3 in the direction of the second sensor 5, which second filter filters out light of a certain wavelength range. The second filter 11 can be designed as an IR filter (infrared filter or infrared absorption filter) which prevents the incidence of infrared radiation.

Interference of the IR radiation with the imaging quality of the first sensor 4 and the second sensor 5 is thereby avoided.

The

sensors

4, 5 can be configured as light-sensitive sensors (image sensors) which first convert the light impinging on the

sensors

4, 5 into voltages which are converted into image data. For this purpose, a not shown transition unit may be provided.

For example, the

sensor

4, 5 or one of the two

sensors

4, 5 can be configured as a CCD (charge coupled device) sensor and/or a CMOS (complementary metal oxide semiconductor) sensor and/or a CIS (contact image sensor) sensor and/or a DPS (digital pixel) sensor. These image sensors have a very high lateral resolution.

Furthermore, the two

sensors

4, 5 or one of the

sensors

4, 5 can also be configured as a PMD (photonic mixer) sensor, which detects the distance of the object in addition to the luminance information of the object. The

sensors

4, 5 may each be of the same or different construction type.

The

sensors

4, 5 or one of the

sensors

4, 5 can also have a photodiode made of silicon. Alternatively, the

sensors

4, 5 can also be made of other semiconductor materials.

The

lenses

2, 3 are arranged on the housing 12. The

lenses

2, 3 may be directed in different directions to take images, i.e. to take different images. However, the captured images may also partially or completely coincide.

The

sensors

4, 5 are arranged in a housing 12. The first sensor 4 is arranged outside the second light beam _ B7, i.e. the light of the second light beam _ a incident through the second lens 3 does not reach the first sensor 4.

The second sensor 5 is arranged outside the first light beam _ B6, i.e. the light of the first light beam _ a entering through the first lens 2 does not reach the second sensor 5.

The first lens 2 and the first sensor 4 form a first optical axis 25. The second lens 3 and the second sensor 5 form a second optical axis 26. The first and

second sensors

4 and 5 and the first and

second lenses

2 and 3 are arranged such that the first and second

optical axes

25 and 26 intersect in the housing 12. This means that the first radiation path 6 and the second radiation path 7 partly overlap in the housing 12.

The

sensors

4, 5 and the

lenses

2, 3 are respectively placed orthogonally to each other.

It is thereby particularly simple to ensure that the light of the first light beam _ B6 does not impinge on the second sensor 5 and that the light of the second light beam _ B7 does not impinge on the first sensor 4.

A first metal layer is arranged between the housing 12 and the first sensor 4, so that the first sensor 4 is electrically conductively connected to the first metal layer. Preferably, the first metal layer is designed as a flexible printed circuit board 13. This saves costs for conventional connecting materials, such as cables or plugs, which are required between two rigid printed circuit boards. This results in a higher reliability than, for example, a cable-circuit board connection or a plug-circuit board connection. Furthermore, due to the flexibility, it is easy to assemble and integrate in the housing 12.

A second metal layer is arranged between the housing 12 and the second sensor 5, so that the second sensor 5 is electrically conductively connected to the second metal layer. Preferably, the second metal layer is a flexible circuit board 13.

All the sensor elements of the camera device 1 can thus be placed on a coherent, flexible printed circuit board.

Alternatively, a circuit board assembly having a plurality of circuit boards connected to each other may be used instead of the flexible circuit board 13.

Preferably, the housing 12 is formed of a non-conductive material that also serves as a carrier substrate for the flexible circuit board 13. The housing 12 has a housing inner side 14 and the circuit board 13 has an inner side 23. In order to avoid reflections of the light beams _ B6, 7, the housing inner side 14 and optionally also the inner side 23 of the circuit board 13 can be provided with a radiation-absorbing layer, for example a black protective lacquer.

The flexible printed circuit board 13 has a bending section 15.

Furthermore, a circuit board fastening element 16, a so-called mechanical guide pin, is provided in order to ensure the positioning of the flexible circuit board 13 in the housing 12. The circuit board fastening element 16 can be made of a light plastic, which is non-conductive and corrosion-resistant, for example. Alternatively, the flexible circuit board 13 may be fixed in the housing 12 by adhesion. The flexible printed circuit 13 can also be fixed in the housing 12 by a screw connection and can thus be rigidly connected to the housing 12. Other methods of fixation are also possible.

The first sensor 4 is designed to convert the first light beam _ B6 impinging on the first sensor 4 into first ambient image data and the second sensor 5 is designed to convert the second light beam _ B7 impinging on the second sensor 5 into second ambient image data.

Furthermore, the camera device 1 has a data transfer interface 17, via which the first and second ambient image data can be transferred for further processing outside the housing 12. The data transfer interface 17 may be designed as a MIPI interface or POC interface, for example.

Furthermore, the camera device 1 can be designed as a camera.

Fig. 3 shows a further camera device 1a according to the invention. The second camera device 1a likewise has a first lens 2, a first filter 10, a first light beam _ B6 impinging on the first sensor 4.

The camera device 1a likewise has a second lens 3, a second filter 11, and a second light beam _ B7 which impinges on the second sensor 5.

Further, the camera device 1a includes: a third lens 18 having a third filter 19; a third light beam _ B20, which impinges on a third sensor 21. The third lens 18 and the third sensor 21 form a third optical axis 27.

The first sensor 4, the second sensor 5 and the third sensor 21 are each positioned substantially at an angle of 120 ° with respect to one another.

The first lens 2 is positioned relative to the first sensor 4 such that the first light beam _ B6 generated by the incident first light beam _ A8 does not reach the second sensor 5 or the third sensor 21.

The second lens 3 is positioned relative to the second sensor 5 such that the second light beam _ B7 generated by the incident second light beam _ A9 does not reach the first sensor 4 or the third sensor 21.

The third lens 18 is positioned relative to the third sensor 21 such that the third light beam _ B20 generated by the incident third light beam _ a 22 does not reach the first sensor 4 or the second sensor 5.

The first sensor 4, the second sensor 5 and the third sensor 21 are arranged in the housing 12. The first lens 2, the second lens 3, and the third lens 18 are disposed on the housing 12.

The first optical axis 25, the second optical axis 26 and the third optical axis 27 intersect in the housing 12. The first light beam _ B6, the second light beam _ B7 and the third light beam _ B20 partially overlap in the housing 12.

The first sensor 4, the second sensor 5 and the third sensor 21 are arranged on the flexible circuit board 13. The flexible printed circuit board 13 has a bending section 15.

The first sensor 4 and/or the second sensor 5 and/or the third sensor 21 can be designed as a one-dimensional, two-dimensional or three-dimensional image sensor.

Also arranged in the housing 12 is evaluation electronics 24. The evaluation electronics 24 are used for data preprocessing of the first, second and third ambient image data generated by the first, second and

third sensors

4, 5, 21, respectively. This results in a shift of the computationally intensive data preprocessing to the location of the data generation. Data reduction can also be achieved during preprocessing. A plausibility check and, if necessary, data correction can also be carried out. Evaluation electronics 24 are connected to data transfer interface 17 for transferring the preprocessed ambient image data for further processing outside housing 12.
